HEATING STOVE.

Application filed May 7',

To aZZ whom it may concern:

Be it known that I, MYRON W. MGCUL- LOUGH, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Heating Stove, of which the following is a full, clear, and exact description.

This invention relates to heating stoves and particularly to an attachment adapted to be built in original stoves or to be added to stoves already on the market, the structure being such that a maximum amount of heat radiation is secured.

Another object of the invention is to provide an attachment for heating stoves wherein the effective radiation area of the stove is enlarged and at the same time the heated air is discharged with some force.

A still further object of the vinvention is to provide an improved attachment for heating stoves wherein air surrounding the stove may be drawn in, heated and discharged from the upper part of the stove in addition to providing the usual radiation incident to a hot stove.

In the accompanying drawing Figure 1 is a front elevation of a stove with an embodiment of the invention applied thereto, the-upper part of the stove being broken away and shown partially in section to illustrate more clearly the con struction.

Figure 2 is a sectional view through Figure 1, approximately on line 2-2.

Referring to the accompanying drawing by numerals, 1 indicates a heating stove of the type which is adapted to be placed in a room and spaced from the surrounding objects so that the heat may be radiated therefrom for properly warming the atmosphere of the room. Where the stove 1 is formed merely with a tire box and a heating drum at the top, the heat is secured through radiation only. In the present invention, however, it is intended to not only utilize the stove as means for radiating heat but to secure the maximum advantage from the fuel by enlarging the radiating surface without enlarging the stove body. In order to do this, an annular ring 2 is provided at the too of the body 3 of the stove 1, said ring being secured in place in any "desired manner but is preferably made air-tight. A tubular member or drum 4 is riveted or 1923. Serial No. 637,213.

otherwise rigidlysecured to the inner edge of the ring 2 and extends downwardly to near the fire box of the stove where it is formed with a closed bottom 5. By reason of this construction, the flame and smoke from the fire box may pass upwardly and impinge against the bottom 5 as well as against the side walls of the drum 4 before it passes out the smoke pipe. In this way, all parts of the drum I are heated but the bottom 5 receives the greatest heat.

The body 3 is provided with an ornamental cover 6 at the top which is formed with openings 7 whereby cool air from the room may enter and pass downwardly into the space 8. A heated air discharge tube 9 is arranged centrally of the drum l and spaced therefrom whereby the chamber or space 8 is provided. The tube 9 is open at the top and bottom so that the heated air may freely pass therethrough. At the bottom, the tube 9 is flared at 10 whereby cool air passing downwardly through chamber 8 will be forced outward and downward in order to cause the same to be forced into as close contact with the bottom 5 as possible and in that way absorb a maximum number of heat units before rising through the tube 9. At the upper end, the tube 9 is riveted or otherwise secured to an ornamental cover 11 which is provided with suitable apertures 12. This cover rests on top of the cover 6 and causes the heated air to be discharged slightly above the stove. It will be noted that the air is gradually heated as it passes downwardly through the chamber 8 and receives this maximum heat as it passes over the bottom 5 whereupon the superheated air passes upward through the tube 9 with some force and is, therefore, projected a considerable distance from the stove by this force before it gradually mixes the air of the room.

It will be understood that the device may be incorporated in a stove when the same is first manufactured and when incorporated, the parts will appear substantially as shown in Figure 1. In case it is applied to an old stove, the drum 4 is preferably made of a size to fit into the usual top opening and the tube 9 is made smaller. Preferably, both the drum 4 and the tube 9 are made from comparatively thin sheet metal whereby they will quickly become heated and, consequently, quickly heat the air passing through chamber 8 or through tube 9- What I claim is: i

In a heating stove of the character described, a solid ring secured at its outer edge to the top of the body of the stove in such a manner as to be airtight, a drum open at the top and closed at the bottom secured to said ring for filling the bore thereof said open end facing upwardly, a covering structure for said body having openings permitting the entrance ot-air into said drum, a tubular cheated air discharge member arranged in said drum and extending to near the bottom thereofl the bottom endoii said tubular memcovering member so as to act as a support for the tubular member, said second mentioned covering member being formed with openings whereby air passing upwardly through the tubular member may be discharged above the first mentioned covering member.
